In the latter sense it is used by Plautus—

“Quia sorbitione faciam ego te hodie mea

By the use of this word I wish to be distinctly understood as

expressing only certain _effects_, without any regard to the causes

that may produce them. The phenomena of _Accumulation_ may on some

occasions depend upon the absolutely increased quantity of the

substance in the body, as in the instance of mercurial action, while

in others they may perhaps arise from the system becoming more and

more sensible to its stimulus. The history of Poisons would afford

some interesting illustrations of these views, and in another work

(Medical Jurisprudence, Vol. 2, p. 148), I have proposed a subdivision

of these bodies, under the title of “_Accumulative_ Poisons.”

The Mechanical Physicians attempted to adjust the doses of medicines

“the doses are as the squares of the Constitution.” And in the

Edinburgh Medical Essays, there is actually a formal attempt to

correct the errors of this rule. See “An Essay towards ascertaining

the doses of vomiting and purging Medicines, by Dr. CHARLES BALGUY,

Physician at Peterborough.” Vol. 1. 167.

Footnote 293:

While this sheet was passing through the press, an anecdote was

related to me, which is well calculated to illustrate the mischief

that may arise from abbreviated prescriptions. One of our most eminent

surgeons having occasion to direct the application of a Lead Plaster

(Emplast: Lythargyi. P. L. 1787), he abbreviated the term as

follows—_Emp. Lyth:_ in the haste of compounding, the _h_, perhaps

carelessly written, was easily mistaken for _t_, and the chemist

accordingly sent the _Emplast: Lyttæ_! As it was applied to the

Pudenda, it is not necessary to state the distress of the patient, and

the dismissal of the practitioner, which followed.

Camphor, unless it be presented to the stomach in a state of minute

division, is liable to occasion heat and uneasiness in that organ.

Footnote 295:

In some cases the subject to be pulverized has been previously exposed

to heat, but the doubtful influence of exalted temperature upon

vegetable bodies, ought to afford us a lesson of extreme caution; the

astringency of the stalks of the Artichoke is entirely destroyed by

being gently heated in an oven, for after this operation they no

longer strike a black colour with the salts of iron: another example

is afforded us in the effects of heat upon Starch, which is thus

changed into a species of gum, no longer producing a blue colour with

Iodine, and which is known in commerce under the name of “British

Gum.”

Footnote 296:

It is perhaps not generally known, that the sugared plumbs sold to

children consist very frequently of Plaister of Paris; the

introduction of such a substance into the intestines may often prove a

source of mischief. I also understand, that it is no uncommon fraud to

adulterate biscuits with the same substance. I confess I felt a great

inclination to oppose the practice, lately suggested, of improving bad

flour by the addition of Magnesia; I object to the introduction of any

foreign and insoluble substance into our daily bread, and I am

satisfied that the result of medical experience will sanction such an

objection.

There is one circumstance which sometimes renders the powder of

liquorice objectionable upon such occasions; it is liable to irritate

the fauces and occasion coughing: for this reason I always avoid its

use in cases of pulmonary irritation.

Footnote 300:

Some extracts become so hard, that in the state of pill they pass

unchanged; this has occurred to me with the _extract of logwood_.

Astringent vegetable matter, in combination with iron, is frequently

characterised by a hardness that is not exceeded by ebony, and which

is perfectly insoluble; the action of iron upon the petals of the red

rose furnishes a very striking instance of this fact; if the petals be

beaten in an iron mortar, for some hours, they ultimately become

converted into a paste of an intensely black hue; which, when rolled

into beads and dried, is susceptible of a most beautiful polish, still

retaining the fragrance of the rose. I have seen a necklace of this

description; indeed these beads form an article of extensive commerce

with the Turks, and are imported into Europe, through Austria, under

the name of _Rose Beads_ or _Rose Pearls_.

In my Lectures I have usually employed different colours for the

upon this plan.

_In these Formulæ the Bark is decomposed, by the alkali; the

Footnote 317:

_This formula is introduced, as a combination supported by authority,

although it may be questioned whether its adoption can be sanctioned

upon principle. Let us decypher the intention of the different

ingredients by their_ KEY LETTERS. _The basis is Squill, to which

Digitalis is added, for the purpose we perceive of acting in unison

with it, and Calomel, which succeeds it, is intended to promote and

direct the diuretic Basis; two fœtid gums next present themselves to

our notice, and these are shewn by the bracket to exert a combined

action, depending, as the Key Letter announces, upon the medicinal

similarity, but acting in the general scheme of the formula, as shewn

by the exterior letter, for the purpose of fulfilling a second

indication, distinct and different from that which the Basis is

designed to answer, i. e. to produce, not a diuretic, but an

antispasmodic and stimulant effect; an important question then arises

for our consideration—Is the latter part of the formula consistent

with the former, or is the stimulant effect of the Gums compatible

with the sedative operation of Digitalis?_

Footnote 319:

Dr. Maton, in his appendix to Mr. Lambert’s work on the genus _Pinus_,

observes that the _Thus_ of the ancients, (λὶβανος) does not appear to

have been the product of any species of Pinus, although we are

informed by Dioscorides (Lib. 1. c. 7.) that Pine resin was often

substituted for it. He describes, moreover, a method of distinguishing

between the two kinds; “Resin of the Pine,” says he, “when thrown into

the fire dissipates itself in smoke, whereas Frankincense burns with a

brisk flame, and with an odour that serves to detect the imposition.”

“Some authors, adds Dr. Maton, have considered the genuine λὶβανος

(_Thus_) to have been obtained from the Juniperus Lycia, and to

constitute the Olibanum of our shops, but I cannot find any passage in

the ancient authors sufficiently precise to corroborate this

conjecture.” Op: citat:

Mouldiness is a peculiar plant, propagated by seeds, infinitely small;

Reaumur found the interior of an addled egg mouldy, hence the seeds

may be prevented by the presence of aromatic substances. See p. 177,

Vinegar quenches the thirst, and is particularly refreshing after much

bodily exertion. It was this property that invigorated the soldiers of

Hannibal in their progress over the Alps; it is absurd to imagine that

Livy meant to assert that the rocks were _dissolved_ by Vinegar: the

expression is only metaphorical. See Sodæ Murias.

Footnote 325:

The varieties of vinegar known in commerce, are three, viz. _Wine_

Vinegar, _Malt_ Vinegar, and _Sugar_ Vinegar; to which may now be

added that from wood, and which is described under the title of ACIDUM

ACETICUM FORTIUS, or Acidum Aceticum, _e ligno destillatum_.

Footnote 326:

I apprehend that the superior power of animal charcoal, over that of

vegetable origin, in removing colouring matter, depends upon the

peculiar texture of the former. At the same time it must be

acknowledged, that there are certain phenomena which would appear to

indicate the existence of a chemical difference in these substances;

thus if Lime water be boiled with _animal_ charcoal, the whole of the

lime will be abstracted from the water, whereas the same effect is not

produced by the action of charcoal of _vegetable_ origin. See Liquor

Calcis.

Footnote 327:

The Sulphuric acid is added for the purpose of preserving the vinegar

from decomposition.

Footnote 328:

This quantity includes the alkali necessary to saturate the Sulphuric

acid which is allowed to be added. 145 grains of alkali is the

standard fixed by act of Parliament, which will be found to coincide

with the atomic weights of these bodies.

Footnote 329:

By _real_ Acetic acid is meant such an acid as occurs in a dry

acetate; it cannot exist uncombined with water, or a base.

Footnote 330:

This is a very ancient preparation, thus Ausonius,

“Scillato decies si cor purgeris aceto

Anticipitesque tuum Samii Lucomonis acumen.”

Footnote 331:

In following the directions of the College the first pint is rejected,

and this, according to Mr. Phillips (Remarks on the Pharmacopœia)

contains a notable quantity of acid. Hence Distilled Vinegar can never

be so strong as the Vinegar from which it is distilled.

Footnote 332:

Or it may be detected, in very minute quantities, by the elegant test

lately employed by Dr. Marcet, and which I have frequently repeated in

my Lectures with considerable satisfaction. It consists in adding a

little sulphuric acid with a small quantity of muriate of soda, and

then immersing a little gold leaf in the mixture, when after boiling

it, if any nitric acid should have been present, the gold leaf will be

dissolved.

Footnote 333:

It had been long known that by the destructive distillation of any

kind of wood, an acid is obtained, which was formerly considered of a

distinct and peculiar nature, and termed Acid Spirit of Wood, and

afterwards Pyroligneous Acid. Glauber appears to have been the first

chemist who was aware of its true nature, for he speaks of it as the

“Vinegar of Wood.” It was however reserved for Fourcroy and Vauquelin

to demonstrate its composition by experiment, and they have

accordingly proved beyond doubt that it is merely the Acetic acid,

contaminated with Empyreumatic oil and Bitumen. The address of modern

chemists has at length enabled them to get rid of every trace of these

latter ingredients, and to furnish an acid perfectly devoid of any

foreign flavour. The crude pyroligneous acid, as it is first received,

is rectified by a second distillation in a copper still, in the body

of which about 20 gallons of viscid tarry matter are left from every

100. It has now become a transparent brown vinegar, having a

considerable empyreuma; it is then redistilled and saturated with

quick-lime, and the liquid acetate is evaporated to dryness and

submitted to gentle torrefaction, in order to dissipate the

empyreumatic matter, and lastly the calcareous salt is decomposed by

sulphuric acid, when a pure, perfectly colourless, and grateful

vinegar rises in distillation.

Footnote 334:

This instrument was invented by Messrs. Taylors for this particular

purpose; the principle consists in forming a neutral salt with dry

hydrate of lime and the acid to be examined, and then taking the

specific gravity of the solution. Act 58. G. III. c. 65, § 8.

Footnote 335:

It may be necessary to state, that the Pharmaceutist should never

purchase acetic acid of greater strength than that of 75° of the

Acetometer, when it is intended for dilution, for although he might

thus avoid the expense of carriage, the saving will be more than

counterbalanced by the excessive duty levied upon acids above that

standard. There is moreover a great loss in the preparation of strong

acids, so that the manufacturer cannot afford to sell them at a price

which is merely proportional to their strength. Acid of 75° is

regularly kept by Messrs. Beaufoy for dilution, and if mixed with

eleven parts of pure water is equivalent to the common distilled

vinegar of the Pharmacopœia.

Footnote 336:

It ought to have been 1·048 of 55° Fah: but the error lies in the

scale of Taylor’s Acetometer, which appears to be incorrect at this

point.

Footnote 337:

I believe that no manufacturer, except Messrs. Beaufoy, makes an acid

stronger than this; the College sample was obtained from that house.

Footnote 338:

The Reviewer of Mr. Phillip’s Translation of the Pharmacopœia, in the

Royal Institution Journal for July, 1824, has fallen into an important

error upon this subject, against which it may be necessary to caution

the reader; he says, “the term ‘_diluted acetic acid_’ is properly

enough applied to Distilled Vinegar, but the process of distillation

might well have been rejected; for all medical purposes a dilute acid,

composed of one part of the concentrated acid, contained in the

Materia Medica, and four parts of water, is preferable. Of this

mixture, or of distilled vinegar, the specific gravity should be

1·009, and 1000 grains should saturate 145 grains of Sub-carbonate of

Soda.” The reviewer has mistaken the acid of sp. gr. 1·043 mentioned

by Phillips, as the strongest he has met with, for the Pharmacopœia

acid of sp. gr. 1·046; for, should he dilute the latter with only four

times its weight of water, he would produce a compound containing

5·686 per cent. of real acid, or one considerably stronger than the

strongest malt vinegar, and twice the strength of distilled vinegar.

The reviewer takes this occasion to indulge his favourite passion for

abusing the Pharmacopœia, and he asks with an air of sarcasm, Where

was Dr. Paris during the late revision? I answer—engaged in the

discharge of my duty as a humble member of the Committee, and I can

assure him that nothing which he has yet urged has convinced me that I

have failed in its fulfilment, or erred in its execution:—but it is

now my turn to enquire, and I do so with perfect good humour, where

the reviewer could have been when he composed the above passage? that

he was _not at home_, is I think sufficiently evident from the

statement which I have just offered.

Footnote 339:

A very useful practical application has been made of the Pyroligneous

Acid, for the purpose of correcting the excessive fœtor attendant upon

mortification. Dr. Samuel W. Moore of this city, (to whom we are

indebted for the suggestion,) has detailed the particulars of a case

of extensive mortification of the cheek, resulting from the use of

mercury, in which the acid was applied, and with the happiest success.

In a case of cancerous breast, it was also used with the same object,

and with similar effect. The mode of using it is simply to apply

pieces of lint or linen wet with the acid to the part affected. See

New-York Medical Repository, Vol. 22. p. 237.—_Ed._

Footnote 340:

AROMATIC VINEGAR is merely an acetic solution of camphor, oil of

cloves, of lavender, and of rosemary. The acetic acid used for this

purpose is about 145° of the acetometer, containing 68·5 per cent. of

real acid. A preparation of this kind may be extemporaneously made by

putting ʒj of Acetate of Potass into a phial with a few drops of some

fragrant oil, and in m xx of Sulphuric Acid.

THIEVES VINEGAR, or MARSEILLES VINEGAR, is a pleasant solution of

essential oils and camphor, in vinegar; the Edinburgh Pharmacopœia has

given a formula for its preparation under the title of “Acetum

Aromaticum.” The repute of this preparation as a prophylactic in

contagious fevers is said to have arisen from the confession of four

thieves, who, during the plague of Marseilles, plundered the dead

bodies with perfect security, and, upon being arrested, stated on

condition of their lives being spared, that the use of Aromatic

Vinegar had preserved them from the influence of contagion. It is on

this account sometimes called “Le Vinaigre des quatre voleurs.” It was

however long used before the Plague of Marseilles, for it was the

constant custom of Cardinal Wolsey to carry in his hand an orange,

deprived of its contents, and filled with a sponge which had been

soaked in vinegar impregnated with various spices, in order to

preserve himself from infection, when passing through the crowds which

his splendour or office attracted. The first Plague raged in 1649,

whereas Wolsey died in 1531. The French Codex has a preparation of

this kind, consisting of an acetic infusion of various aromatic herbs

and camphor, which is termed “Acetum Aromaticum Alliatum,” seu

“Antisepticum” _vulgo_ “des Quatre Voleurs.” p. 108. The German

Dispensatories abound with Medicated Vinegars, chiefly aimed against

Pestilential Diseases.

Footnote 341:

The more familiar of these are _Bitter Almonds_, the _Cherry Laurel_

(Lauro Cerasus,) the leaves of the _Peach tree_, the kernels of fruit,

pips of apples, &c. The prussic acid would appear to be most abundant

in the thin pellicle that envelopes the kernel; the fleshy parts of

these fruits do not contain it, and even the berries of the _Lauro

Cerasus_ may be eaten with impunity; and yet the distilled water, and

oil of this plant are the most destructive of all narcotic poisons, as

was evinced by the murder of Sir Theodosius Broughton, by Laurel

Water; and by the untimely fate of Dr. Price, of Guildford, in the

year 1782, who professing to convert Mercury into Gold, offered to

repeat his experiments before an adequate tribunal, but put a period

to his existence before the appointed day, by a draught of Laurel

Water. Consistent with theory, the watery extract of Laurel is

harmless, a fact easily explained, since the narcotic acid is entirely

volatilized before the fluid can assume the consistence of an extract.

The Laurel Water as a medicinal agent appears to have been long known.

Linnæus, informs us that it was frequently used in Holland, in

pulmonary consumption. (_Amænitat. Academ._ vol. iv. p. 40.) The Bark

of the _Prunus Padus_, or Bird Cherry Tree, was ascertained to contain

Prussic acid, by M. Bergemann, in 1811, and it is certainly a curious

fact, as Dr. Granville has observed, that superstitious people should

have selected the berries of this shrub to form necklaces, which are

hung round the neck of children to prevent fits and allay cough from

teething. For farther information upon this subject, the reader may

consult “The Chronological recapitulation respecting the Introduction

of the Prussic acid into the Practice of Physic,” in the work of Dr.

Granville, above cited.

For a detailed account of this poison, see my work on Medical

Jurisprudence, vol. ii. p. 398.

Footnote 344:

It seems to be a contest for a shadow.

Footnote 345:

We agree with our author in the general estimate which he forms of the

Prussic Acid. The experience of practitioners in this country has by

no means confirmed the high expectations originally entertained of

this article. _Ed._

Footnote 346:

The only mineral substances in which this acid has been found is the

_Fer Azuré_ of Haiiy, and a new substance which is found accompanying

Welsh Culm, and of which I have given an account in the first volume

of the Transactions of the Royal Geological Society of Cornwall,

although in this latter instance it is probably a product, not an

educt.

Footnote 347:

The following is the chemical reasoning upon which this process is

founded. “The prime equivalent of prussic acid is exactly one-eighth

of that of the mercurial peroxide. But as the prussiate of mercury

consists of two primes of acid to one of base, or is in its dry

crystalline state a _By-cyanide_, we have the relation of one to four

in the formation of that salt, when we act on the peroxide with cold

prussic acid.” Hence is derived the above simple rule of analysis.

(Journal of Science and the Arts.) Upon the same principle it has been

already stated, that the quantity of real acetic acid, in any given

sample of distilled vinegar may be discovered by the test of carbonate

of lime, see _Acid. Acetic. Fort._ They furnish beautiful

illustrations of the practical importance of the doctrine of Definite

Proportions.

Footnote 348:

This offers a striking example of the confusion produced by the

constant changes in chemical nomenclature; in the former editions of

this work, the term _Hydro_ was prefixed to _Muriatic Acid_, as an

epithet expressive of the presence of _water_, whereas the same word

is now used to denote the existence of _Hydrogen_ as one of its

elements.

Footnote 349:

Dr. Powell directs only _two_ parts of acid; but this is evidently too

little, for it appears by Dr. Wollaston’s scale, that 3 parts of salt

require 2½ of oil of vitriol for their decomposition; and in addition

to this, the oxide of manganese will require a farther addition to

convert it into a sulphate.

Footnote 350:

As Chlorine is by pressure condensable into a liquid, tubes containing

a small quantity of it, and hermetically sealed, might be very

usefully employed for this purpose, since by breaking off the

extremity, the chlorine would instantly assume the gaseous state, and

diffuse itself through the apartment.

Footnote 351:

There is a curious illustration of this fact in the German

“_Ephemerides_;” the case of a person is described who had taken so

much Elixir of Vitriol that his keys were rusted in his pocket, by the

transudation of the acid through his skin!

Footnote 352:

Nitric acid may be considered as one of the most efficient agents in

our possession for exciting prompt vesication. For this purpose, we

believe it was first used in the epidemic Cholera of the East Indies,

and the success which attended it in that fatal disorder suggested its

application in a variety of other diseases. The mode of using it is to

rub the surface intended to be vesicated, with the pure acid, and as

soon as pain is produced, to neutralize the acid by washing the part

with a solution of salt of tartar. If the object is to continue the

irritation, a common blister may be laid upon the part. _Ed._

Footnote 353:

_Nitrous acid gas_ is a combination of nitrous gas and oxygen.

Footnote 354:

ELIXIR OF VITRIOL. The preparation sold under this name is the Acid:

Sulph: Aromat: E. and is imperfectly ætherial in its nature. It is a

nothing but the diluted acid, coloured by the addition of a tincture.

I will take this occasion to state, that the term Elixir is of Arabian

origin, viz. Elechschir, or Elikscir, i. e. an Essence, or pure mass

without any dregs.

Footnote 360:

Garlic, leeks, and onions constitute a tribe of culinary vegetables

that has undergone great vicissitudes in reputation: amongst the

Egyptians the onion and leek were esteemed as divinities, thus

Juvenal,

“O sanctas gentes quibus hæc nascuntur in hortis

NUMINA!”

while by the Greeks, garlic was detested, although their husbandmen

had been from the most remote antiquity in the habit of eating it,

which Æmilius Macer explains by supposing that its strong odour was

useful in driving away the venomous serpents and insects by which they

were infested.

Horace alludes to this custom in his 3d Epode, which he composed in

consequence of having been made violently sick by garlic at a supper

with Macænas.

“Cicutis Allium nocentius

O dura Messorum ilia!”

The most powerful antidotes to the flavour of this tribe of vegetables

are the aromatic leaves and seeds of the UMBELLIFERÆ; thus the

disagreeable odour of a person’s breath after the ingestion of an

onion is best counteracted by parsley; and if leek or garlic be mixed

with a combination of aromatic ingredients, its virulence will be

greatly mitigated and corrected, nor does the fact seem to have

escaped the observation of the husbandman in Virgil,

“Allia, Serpyllumque, herbas contundit olentes.”

And the fact itself offers an additional illustration of the important

principle of combination, discussed at page 148.

From the action which aloes exercises over the large intestines it has

of hemorrhoids. It would seem hardly possible that an opinion, so

generally received, could be without some foundation; and, no doubt,

in many cases it may produce such an effect. In my own experience,

however, I do not recollect to have met with it in a single instance,

even where its use had been continued for several months in

succession.

HOOPER’S PILLS.—Pil. Alöes cum Myrrha, (Pil. Rufi) Sulphate of Iron,

and Canella Bark, to which is added a portion of Ivory Black.

DIXON’S ANTIBILIOUS PILLS.—Aloes, Scammony, Rhubarb, and Tartarized

Antimony.

SPEEDIMAN’S PILLS.—Aloes, Myrrh, Rhubarb, Extract of Chamomile, and

some Essential Oil of Chamomile.

DINNER PILLS—LADY WEBSTER’S, OR LADY CRESPIGNY’S PILL. These popular

pills are the “Pilulæ Stomachicæ,” vulgo, “Pilulæ ante cibum” of the

Codex Medicamentarius Parisiensis. Editio Quinta, A.D. 1758. viz. ℞.

Aloes optimæ ʒvj, Mastiches, et Rosarum rubrarum āā ʒij, Syrupi de

Absinthio q, s, ut fiat massa,—the mass is divided into pills of 3

grains each. The operation of this pill is to produce a copious and

bulky evacuation, and in this respect experience has fully established

its value. It is difficult to explain the modus operandi of the

Mastiche, unless we suppose that it depends upon its dividing the

particles of the Aloes, and thereby modifying its solubility.

FOTHERGILL’S PILLS.—Aloes, Scammony, Colocynth, and Oxide of Antimony.

PETER’S PILLS.—Aloes, Jalap, Scammony, and Gamboge, equal part

ʒij—Calomel ʒi.

RADCLIFFE’S ELIXIR—℞. Aloes Socot: ʒvi, Cort:—Cinnamon et Rad: Zedoar:

āā ʒss—Rad: Rhei ʒi.—Coccinel: ʒss—Syrup: Rhamni f℥ij—Spirit: Tenuior:

oj—Aquæ Puræ f℥v.

BEAUME DE VIE, see Decoct: Aloes compositum.

THE ELIXIR OF LONGEVITY, of Dr. Jernitz of Sweden. This is an aromatic

tincture, with Aloes.

Footnote 365:

The best mode of using alum as a styptic is that of a _tepid saturated

solution_. In this form it proves much more efficacious in arresting

hemorrhage than in the usual way of applying it. Dr. Scudamore, to

whom we are indebted for this observation, has detailed some striking

and interesting experiments satisfactorily proving its correctness.

See “Scudamore on the Blood.” p. 157.—_Ed._

Footnote 366:

GODFREY’S SMELLING SALTS. This highly pungent preparation is obtained

by resubliming the common sub-carbonate of ammonia with pearlash, and

a proportion of rectified spirit. The sub-carbonate of potass in this

case, abstracts a fresh portion of carbonic acid from the ammoniacal

salt. Its atomic composition has not yet been ascertained, but it will

probably be found to consist of equal atoms of carbonic acid and

ammonia, and must therefore be a true Carbonate.

Footnote 367:

It appears that this is not the only article that has suffered in its

quality by the cheap materials which have been brought into the market

from those works. I understand that the practical chemist can obtain

little or no Naphtha from the Barbadoes Tar, owing to its adulteration

with the residue of the gas light process.

Footnote 368:

NOYAU.—Crème de Noyau. Bitter Almonds blanched 1 oz. Proof spirit half

a pint, Sugar 4 oz. It is sometimes coloured with cochineal. The

foreign Noyau, although differently prepared, is indebted to the same

principle for its qualities. It is a liqueur of a fascinating nature,

and cannot be taken to any considerable extent without danger; the

late Duke Charles of Lorraine nearly lost his life from swallowing

some “Eau de Noyau,” (water distilled from Peach kernels) too strongly

impregnated. Journal des Debats, 22, Decembre, 1814.

Footnote 369:

ALMOND PASTE. This Cosmetic for softening the skin and preventing

chaps, is made as follows: Bitter almonds blanched 4 oz.; the white of

an egg; rose water and rectified spirit, equal parts, as much as is

sufficient.

Footnote 370:

For the derivation of this term, and remarks thereon, see p. 38.

(Note).

Footnote 371:

The fecula of various grains are employed as articles of diet for the

sick, e. g. SAGO, prepared from the pith of the Cycas Circinalis, its

granular form is imparted to it by passing it, when half dry, through

a coarse sieve. SALOP, from the Orchis Mascula. TAPIOCA from the root

of the Jatropa Manhiot. By expressing the root of this plant, the

juice of which is extremely acrid, and baking the cake that is left,

an alimentary substance is prepared called CASSAVA, the peculiar merit

of which, like tapioca, is to swell and soften in water, and thus to

make an excellent pudding. ARROW ROOT is from the Maranta Arundinacea.

The arrow root however, usually sold, is the fecula of potatoes; 100

lbs. of which would yield about 10 lbs. of fecula, and it is worthy of

remark that for this purpose frozen potatoes answer as well as those

not spoiled by the frost. Dr. Ainslie, in his Materia Medica of

Hindostan, informs us that “an excellent Arrow root, if it may be so

called, is now prepared in the Travancore country from the root of the

Curcuma Angustifolia, no way inferior to that obtained from the

Maranta Arundinacea.”

Footnote 372:

The method of deducing the value of seeds, from their relative

weights, appears to have been one of the earliest instances of the art

of taking specific gravities; thus Pliny (Nat. Hist. lib. xviii.)

estimated the relative weights of several species of grain.

Footnote 373:

CHAMOMILE DROPS. The nostrum sold under this name is a spirit

flavoured with the essential oil of Chamomile. It is very obvious that

it cannot possess the bitter tonic of the flowers.

Footnote 374:

THE EVERLASTING PILL of the ancients consisted of _metallic_ Antimony,

which being slightly soluble in the gastric juice was supposed to

exert the property of purging as often as it was swallowed. This was

economy in right earnest, for a single pill would serve a whole family

during their lives, and might be transmitted as an heir-loom to their

posterity. We have heard of a Lady who having swallowed one of these

pills, became seriously alarmed at its not passing; upon sending

however for her physician, he consoled her with the assurance that it

had already passed through a hundred patients with the best effect.

Footnote 375:

The manner of doing it among the Turks, is described by Shaw and

Russel. Chateaubriand also remarks, “The women of Athens appear to me

smaller and less handsome than those of the Morea, their practice of

painting the orbits of the eyes blue, and the ends of the fingers red,

is disagreeable to the stranger.” Dr. Badham has also given us an

interesting note upon this subject in his learned Translation of

Juvenal. Sat. II. 1. 141. See also the present work, p. 49.

Footnote 376:

The Sulphuret of Antimony is an ingredient in SPILSBURY’S DROPS. See

Hydrargyri Oxy-murias. Dr. Duncan also observes that it seems to

constitute a quack remedy which has acquired some reputation in

Ireland for the cure of cancer, where it is used as an external

application to the sore.

Footnote 377:

This saline body was first made known by Adrian de Mynsicht in his

Thesaurus Medico-chymicus, published in 1631; although it appears

probable that the preparation was suggested by a treatise, entitled

“Methodus in Pulverem,” published in Italy in 1620. This book, written

by Dr. Cornachinus, gives an account of a method of preparing a powder

which had been invented by Dudley, Earl of Warwick, and which had

acquired considerable celebrity in Italy; this powder was composed of

Scammony, Sulphuret of Antimony, and Tarter, triturated together.

Footnote 378:

There is a Tartrate of Antimony, but it can scarcely be made to

crystallize; it easily assumes a gelatinous form; and it may be here

observed that Antimony is one of those metals whose oxides seem to

combine with difficulty, and to form compounds of little permanency

with acids, unless there be present at the same time an alkali or

earth; and their solutions, in most cases, yield, on dilution, a white

precipitate.

Footnote 379:

The compound of Tartarized Antimony and Bark, is said to purge, and to

constitute the “Bolus ad Quartanas” of the French physicians.

Footnote 380:

The Sugar is added with a view to prevent the ointment from becoming

rancid.

Footnote 381:

NORRIS’S DROPS. A solution of tartarized antimony in rectified spirit,

and disguised by the addition of some vegetable colouring matter. I am

credibly informed that the original recipe contained opium, but that

which I have examined, and which was procured from a respectable

agent, yielded no indications of its presence.

Footnote 382:

Hard water has a tendency to produce diseases in the spleen of certain

animals, especially sheep: this is the case in the eastern side of the

island of Minorca, as we are informed by Cleghorn. The mischievous

tendency of bad water, where it cannot be corrected by some chemical

process, would seem to be best counteracted by bitter vegetables.

Virey supposes that this circumstance first induced the Chinese to

infuse the leaves of the tea plant.

Footnote 383:

Alpini informs us that Elephantiasis is endemial in Egypt; Galen

ascribes it to the impure waters of the Nile, and Lucretius adopted

the same opinion.

“Est Elephas morbus, qui propter flumina Nili

Gignitur Ægypto in Medio.”

Footnote 384:

Dr. Percival observes that bricks harden the softest water, and give

it an aluminous impregnation; the common practice of lining wells with

them, is therefore very improper, unless they be covered with cement.

Footnote 385:

The same strumous affection occurs at Sumatra, where ice and snow are

never seen; while, on the contrary, the disease is quite unknown in

Chili and Thibet, although the rivers of these countries are chiefly

supplied by the melting of the snow with which the mountains are

covered. The trials of Captain Cook, in his voyage round the world,

prove the wholesomeness of _Ice water_ beyond a doubt; in the high

southern latitudes he found a salutary supply of fresh water in the

ice of the sea; “this melted ice,” says sir John Pringle, “was not

only sweet but soft, and so wholesome as to shew the fallacy of human

reasoning unsupported by experiments.”

Footnote 386:

I take this opportunity of observing that I have made analyses of

several of those springs in Cornwall, which have from time immemorial

enjoyed a reputation in the neighbourhood for curing diseases, amongst

which were the waters of Holywell, so named from its supposed virtues,

and those of Permiscen Bay, equally extolled for their medicinal

qualities. But I have only been able to detect minute quantities of

carbonate of lime, derived from infiltration through banks of

calcareous sand. See Transactions of the Royal Geological Society of

Cornwall, Vol. I.

Footnote 387:

See “Remarks on the Pump water of London,” by W. Heberden, M. D. in

the 1st. vol. of the Medical Transactions; also, Acad. Royale des

Scienc. 1700, Hist. pag. 58. Perrault Vitruve. L. VIII. c. 5.

Footnote 388:

I am informed by a respectable chemist in this town, that he sells a

large quantity of alum for this very purpose, as well as to publicans

for the sake of clearing their spirituous liquors; for the same end,

we are told, that the wine merchants in Paris put into each cask of

wine as much as a pound of alum.

Footnote 389:

This is particularly the case with respect to the water of the River

Thames; for as it contains but a small proportion of saline matter, it

is remarkably soft, although it holds suspended mud, and vegetable and

animal debris, which occasion it to undergo a violent change on being

kept: a large volume of carburetted and sulphuretted hydrogen gases is

evolved, and it becomes black and insufferably offensive; upon racking

it off however into large earthen vessels, and exposing it to the air,

it gradually deposits a quantity of black slimy matter, and becomes as

clear as crystal, and perfectly sweet and palatable, and is

exceedingly well adapted for sea store. “THE NEW RIVER WATER” contains

a small proportion of muriate of lime, carbonate of lime, and muriate

of soda; it differs also in its gaseous contents: 100 cubic inches of

New River Water contain 2·25 of carbonic acid, and 1·25 of common air,

whereas the water of the Thames contains rather a large quantity of

common air, and a smaller proportion of carbonic acid.

Footnote 390:

The law which determines such combinations has been investigated with

singular ingenuity and success by Dr. Murray, (Transactions of the

Royal Society of Edinburgh, 1816). Berthollet had already established

the important fact, that combinations are often determined by the

force of cohesion, in such a manner, that in principles acting on each

other, those on which this force operates most powerfully, in relation

to the fluid which is the medium of action, are combined together;

hence from a knowledge of the solubility of the compounds which

substances form, we may predict what combinations will be established

when they act on each other, those always combining which form the

least soluble compounds. It is for the extension of these views, and

for the useful application of them, that we are indebted to Dr.

Murray, who justly observes that if the force of cohesion can so far

modify chemical attraction, as to establish among compound salts

dissolved in any medium, those combinations whence the least soluble

compound are formed, we are entitled to conclude that the reverse of

this force, i. e. the power of a solvent, may produce the opposite

effects, or cause the very reverse of these combinations to be

established, so that in a concentrated medium the least soluble will

be formed, and in a dilute one, the more soluble compounds will be

established. Hence follows the simple rule by which the actual state

in which saline bodies exist in a solution may be determined, viz.

that in any fluid containing the elements of compound salts, the

binary compounds existing in it will be generally those which are most

soluble in that fluid, and the reverse combinations will only be

established by its concentration favouring the influence of cohesion.

It appears that by simply evaporating a saline solution we may produce

changes in its composition, and obtain products which never existed in

its original state of dilution; thus, suppose muriate of magnesia and

sulphate of soda to be dissolved in water, as is actually the case in

the water of the ocean, and the solution to be concentrated by

evaporation from heat; the combinations of sulphate of magnesia and

muriate of soda, being on the whole less soluble in water, this

circumstance of inferior solubility, or the force of cohesion thus

operating, actually determines the formation of these compounds; and

the production of sulphate of magnesia from the bittern is to be

explained upon this principle. Since it appears therefore that the

influence of solubility is most important, temperature, to whose

dominion it is under all circumstances subject, must necessarily be

alike powerful; let us exemplify this fact by the action of the very

salts under consideration; it has been just stated that muriate of

magnesia and sulphate of soda decompose each other in a concentrated

solution at a high temperature, producing muriate of soda and sulphate

of magnesia, but at temperatures below 32° the reverse actually takes

place, muriate of soda and sulphate of magnesia reacting, and being

converted into sulphate of soda and muriate of magnesia; a fact

evidently owing to the relation of the solubility of these salts to

temperature. Muriate of soda has its solubility scarcely altered,

either by heat or cold; sulphate of soda is, in these respects,

completely the reverse; hence at an elevated temperature, muriate of

soda is the least, and sulphate of soda the most soluble salt, whilst

at a low temperature, the reverse of this happens. All the

circumstances of this investigation are most interesting; the medical

practitioner will at once perceive its importance, as enabling him to

appreciate the real nature of saline solutions, and even in many

instances to preserve their identity. See Aquæ Minerales.

Footnote 391:

There is a precaution respecting the preservation of these waters for

analysis with which the chemist ought to be acquainted; it will be

fully explained by the relation of the following anecdote. M. Wurza,

on examining some bottles of Chalybeate water, could detect no signs

of iron in them, and on seeking for the cause of this circumstance, he

discovered it in the astringent nature of the corks which had combined

with the metallic substance, and abstracted it from the water.

Footnote 392:

The Mineral Springs in the United States more especially deserving of

notice, are those of Saratoga and Ballston in the State of New-York,

and of Schooley’s Mountain in New-Jersey. Of the two first, various

analyses have been published by different chemists, but with so little

uniformity of result as to leave their true chemical character still

in a state of uncertainty. An account of these discrepancies may be

seen in the New-England Journal of Medicine and Surgery for 1817. As

the analyses of Dr. Steel appear upon the whole to be most

satisfactory, we shall quote them. One gallon of the water was the

quantity used in the experiments.
